...), respectively. Photoreceptors from the corresponding retinas of the bay scallop Argopecten irradians had λ max values of 506±1 nm ( N =21) and 535±3 nm ( N =14). Assuming that the proximal and distal receptors had equal absorption coefficients ( k D =0.0067 μm –1 ), we found that self-screening within...

...John M. Olson; Richard L. Marsh ABSTRACT The isometric and isotonic contractile properties of the cross-striated adductor muscle of the bay scallop ( Argopecten irradians ) were measured in vitro at 10, 15 and 20°C. The length at which twitch force was maximal as a function of the closed length...
